They now understood that scientists and science itself make mistakes, as seen in the misreading’s of the caesium levels in the soil. But the farmers too did not promote coexistence with the Scientists, due to the years of “Misunderstood misunderstanding” and the disregard of authority in each groups corresponding field. In conclusion the Chernobyl disaster and

Do you know that you are taking a risk of obtaining cancer and disease every morning when you put on your skin-care and makeup? We all know mercury is often used in all kinds of measuring equipment. Mercury is a highly toxic element that is found both naturally and as an introduced contaminant in the environment (EA, Alhibshi). However, this element is even used in cosmetic products as well. Scientists testing on 73 different cosmetics including face and lip products have found that 44% of face creams

In the early 19th century, scientists all over the world began to study light and colors. In the beginning, not much was known about colors and what caused certain shades to appear. It wasn’t until 1859 when two German scientists created the foundation for the study of spectroscopy and colors (Historical Introduction to Spectroscopy). Robert Wilhelm Bunsen grew a fascination with light when he first observed that certain colors were emitted when chemicals were burned under his flame lamp invention

hundred square kilometres near the nuclear plant have been declared too radioactive for human habitation; these areas are called exclusion zones. When radioactive caesium is introduced to an ecosystem it contaminates the water, soil, plants, animals and maintains ownership of the land for centuries (Starr). Further, radioactive caesium bioaccumulates as it moves up the food chain. Bioaccumulation refers to the build up of chemicals in an organism which can be dangerous for human consumption. Forty

uncontrolled radioactive release ever recorded in history. Chernobyl was an accident that occurred while running routine checks on the Chernobyl 4 reactor on April 26, 1986. The explosion released all of its xenon gas, and about half of its iodine-131 and caesium-137 into the atmosphere. This accident resulted in tens of thousands of deaths and millions left with radiation poisoning. Chernobyl used to be prospering with a population of about 14,000; however, today it's a ghost town with a population hovering

was brought by the prevailing wind to the places such as Belarus, Ukraine, Russia and other parts of Europe. According to the World Nuclear Association, “about half of the iodine and caesium, and at least 5% of the remaining radioactive in the Chernobyl 4 core were released in the accident.” (R5) Iodine-131 and Caesium-137 were the main radioactive that had come in contact with the public. Also, the fact that the radioactive liquid accumulated at the bottom of the reactor and needed three divers to

The main causes of the Chernobyl disaster can be categorized into two sections, which are design flaws and also staff operation errors. In fact, the design flaws existed due to the application of Reaktor Bolshoy Moshchnosti Kanalniy (RMBK) reactor. In general, the reactor core of RMBK is unstable when the energy production is lower than a quarter of maximum power (around 700 MW). In other words, the process control of the reactor is very hard to perform and therefore it has high possibility to have

"Disaster of Fukushima shows that nuclear energy is highly unsafe so, all around the world need to learn from the accident in Fukushima. We need to realize this accident can happen anywhere in the world." (Rianne Tuele, Radiation expert in Green Peace). Originally nuclear energy announced as an alternative energy that is cheap, clean, and safe compare to other existing energy. Therefore, some people insist the nuclear power plants must be kept open but, I disagree with three reasonable safety reasons
